No doubt the Parasound are quality amps and legit bang for buck but Parasound / Simaudio is not a real fair fight.
Simaudio makes some of the best gear on the planet. dynamic, uber-transparent, airy, spacious, big wide and deep sound stage, inky black quiet, extended, tight and clean while being vibrant and colorful with some sheen and inherent warmth. That’s their stick and it is also happens to be the whole ball of wax right there as far as really-really good SS gear. These are not their Evo amps but the word is they sound awfully close.
Parasound is sold stuff but they play in another league. The Sim gear is legit, seriously good and creamy ss gear... No contest what so ever IMO...
